Cl.156- -i -39 Thisinvention relates broadly to screens of the type employed particularlyfor use in con' nection with windows, and more particularly to that typeof screen including a web or sheet of flexible foraminous materialattached .at one end to a spring roller and equipped at the other endthereof for attachment to a window sash.

Among the objects of the present invention is to provide a screen ofthis type which may be readily installed and which, generally, is animprovement upon such screens.

The invention together with its objects and advantages will be bestunderstood from a study of the following description taken in connectionwith the accompanying drawings wherein:

Figure 1 is an elevational view illustrating the application of thescreen with the window sash in raised position.

Figure 2 is a fragmentary vertical sectional view taken substantially onthe line 2-2 of Fig. 1.

Figure 3 is an end elevational view of the screen and housing therefor.

Figure 4 is a fragmentary detail sectional view through thespring-equipped end of the roller, and I Figure 5 is a detail sectionalview taken substantially on the line 55 of Fig. 1.

Referring more in detail to the drawings it will be seen that in thepreferred embodiment of the invention the same comprises an oblonghousing 5 embodying an oblong frame having a top 6, ends I, and a bottom8; the bottom 8 being in the form of a rectangular plate equipped atopposite ends thereof with flanges 9 to which are riveted or otherwisesecured as at the sides 1 of the frame.

Completing the housing there is disposed at the outer side of the frameI an angular wall I I that is integral with the outer longitudinal edgeof the plate 8. The wall H extends vertically upwardly from the plate 8and then is curved inwardly towards the top 6 of the frame, with theupper edge of the wall in intimate contact with the longitudinal edge ofthe top member 6 of the frame, and may be welded or otherwise positivelyunited therewith as found desirable.

It will be seen that this construction and arrangement provide foropenings 12 at opposite sides of the housing whereby access may be hadto the screen and the roller therefor.

The sides 1 of the frame portion of the housing are equipped adjacentone vertical edge thereof to receive the pintles of a roller l3 wherebysaid roller may be easily and quickly mounted in position. I i

As shown in Fig. 14 the roller embodies a core through the medium of acoil spring ll that is convoluted about the-shaft it that extends fromone end of the core l4 through one end of the complete roller. Thespring ll is suitably anchored to the core l4 and to one end ofthe shaftI6, and the tubular part l3 of the roller is equipped to receive'oneendof the shaft [6 as shown. Thus spring'l'l will, as previously stated,cause the parts of the roller as a unit to rotate relative to the shaftfor winding on the roller the web or sheet I8. The web'or sheet I8 is offlexible foraminous material, and at its free end is provided with areinforcing bar I9.

Bar l9 isprovided with eye-bolts 2t adapted to be engaged with hooks 2|provided on the lower rail of the sliding window sash 22 for detachablyconnecting the screen with the window sash.

Also mounted in the frame of the housing is a guide roller 23 over whichthe sheet I8 is trained as clearly shown in Figs. 2 and 3.

In actual practice, the frame portion of the housing 5, and which isslightly longer than the wall ll of said housing, sits on the windowsill between the stops 23, 24, and the entire housing structure isreleasably anchored in position through the medium of pointed anchoringlugs 25 that are pivoted to the top 6 of the frame portion of thehousing as at 26. The pointed ends of the anchoring prongs 25 bite intothe side rails 21 of the window frame and thus serve to properly anchorthe housing in position and against the housing being pulled upwardlyincidental to a raising of the window sash 22.

' I From the above it will be seen that when the device is properlyapplied and the screen sheet l8 connected in the manner shown anddescribed to the lower rail of the sliding sash 22, movement of the sash22 to a raised position will cause the screen web l8 to pay out and thuscover the opening caused by the raising of the Window sash.

Manifestly, as the sash 22 moves downwardly to a closed position thescreen web l8 will wind on the roller I3. I

It is thought that a clear understanding of the construction, operation,utility and advantages of a Window screen embodying the features of thepresent invention will be had without a more detailed descriptionthereof.

Having thusv described the invention what is claimed as new is:

1. In a window screen, an elongated housing member adapted to bepositioned on a window sill between the vertical rails of a window frameand equipped with means for engaging such rails to anchor said housingin'place, a roller journaled in said housing, and a screen Web windableon said roller, said web having a free end reinforced and equipped withmeans for detachably connecting said end to the lower rail of a slidingsash; and said housing comprising a relatively broad flat base plate, aframe rising from said base plate and extending for substantially thefull length of said base plate and including a top member, the membersof said frame being substantially half the width of said base plate, anda Wall plate extending upwardly from the longitudinal edge of the baseplate farthest remote from said frame and having the upper portionthereof biased toward said frame with the upper edge in meeting contactwith the top member of said frame.

2. In a portable screen, a base plate having upstanding flanges atopposite ends thereof and extending from about the longitudinal medianof said plate to one longitudinal edge of the plate, a frame having topand end members, said end members at the lower ends thereof beingsecured to said flanges, a spring roller supported between the endmembers of said frame, a flexible foraminous web windable on saidroller, and a wall-forming plate extending from the second longitudinaledge of said base plate to the top member of said frame.

3. In a portable screen, a base plate having upstanding flanges atopposite ends thereof and extending from about thelongitudinal median ofsaid plate to one longitudinal edge of the plate, a frame having top andend members, said end members at the lower ends thereof being secured tosaid flanges, a spring roller supported between the end members of saidframe, a flexible foraminous web windable on said roller, and awall-forming plate extending from the second longitudinal edge of saidbase plate to the top member of said frame, and anchoring lugs pivotedat one end thereof to the top member of the frame adjacent opposite endsof said top member.

4. In a portable screen, abase plate having upstanding flanges atopposite ends thereof and extending from about the longitudinal medianof said plate to one longitudinal edge of the plate,

a frame having top andend members, said end members at the lower endsthereof being secured to said flanges, a spring roller supported betweenthe end members of saidframe, a flexible: foraminous web windable onsaid roller, and a wall-forming'plate extending from the secondlongitudinal edge of said base plate to thetop member of said frame, andanchoring lugs pivoted at one end thereof to the top member of the frameadjacent opposite ends of said top"
